The cause is unknown. Genes may play a role. Other family members may have the disorder. But panic disorder often occurs when there is no family history.

Panic disorder is twice as common in women as it is in men. Symptoms often begin before age 25, but may occur in the mid-30s. Panic disorder may occur in children, but it is often not diagnosed until they are older.

Many people with panic disorder first seek treatment in the emergency room. This is because the panic attack often feels like a heart attack.

The health care provider will perform a physical exam and a mental health assessment.

Blood tests will be done. Other medical disorders must be ruled out before panic disorder can be diagnosed. Disorders related to substance abuse will be considered because symptoms can resemble panic attacks.
